Charcoal. Charcoal is one of the best substances to absorb smells. You will find that charcoal is used in many air and water filters. Grab a chunk of charcoal, the ones you use to grill will work fine, leave the charcoal in the car for a few days, and you will soon find the smells have gone away because they are absorbed into the charcoal.

In this investigatory project its main purpose is to find out if how can charcoal be used as a filter and how does it work? Since charcoal is made out of carbon. According to Encyclopedia: "The use of special manufacturing techniques results in highly porous charcoals that have surface areas of 300 - 2,000 square meters per gram. Charcoals are widely used to adsorb odorous or colored substances from gases or liquids." The problem with charcoals is that its production efficiencies are generally low, with as much as 60-80% of energy in the wood lost. Adding to this loss is the poor efficiency of many charcoal stoves, some as low as 3%.

Scope and Limitation The scope of this study is that it will be conducted to determine if charcoals can be really used as mufflers or filters and on how does it work. This study will be limited on only the use of charcoal and the different strategies the researches will be using.

Definition of Terms
Charcoal - is a light black residue consisting of carbon. It is usually produced by slow heating of wood or other substances in the absence of oxygen. Adsorb - is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface. Carbon - is a chemical element, all known life on Earth is made from it. It is the only element that can form long chain-shaped molecules. Muffler - is a
